I’m currently going through the Rossmann (lesson 6) notebook and I’m running into some issues with lr_find().

Here’s what I’m supposed to get:

Jeremy used a learning rate of 1e-03 and such a learning rate doesn’t make sense with the graph I received.

I re-ran the notebook and got a slightly different learning rate plot this time:
